T0 all w7wm it may concern:

Be ib known that 1, J OHN Ronoumsof Pittsburg, in tahe county of Allegheny am]. State of Pennsylvania, have invented a new and nse ful Improvement in Bush-(30m1 Fasteners; and I do hereby declare the following to bez. full, clear, and exact description thereof.

'Ihe manner of securing the weighb-oords to window-sashes herctoforein most; comrnon use was to cut a groove in the edge of the sash and bore a hole at a. slightly-upward inclination into the sash at I;he bottom of this groove, into which hole the knotted end of the oord was driven. 1tis a common experience that this arrangement 1's so liable to geb 01113 of Order by the slipping of tl1e cord oub of its hole or by its jamming in the groove or breaking thatib is a oonstanb and fruilaful source of annoyance and inoonvenience. WVhen any ofthese tahings happens, ib is necessary to take out tahe sash to repair the eord, and this involves the removal of the window guides or beads and considerable t-ime and trouble.

My invention is designed to prevent all of these disadvantages and to afford asecure but easily-released fastening for the sashcord, by which tshe cord (Jan be attached or releasecl easily and quiokly wibhoub rernoving the sash or the guides.

T0 enable others skilled in the art to make and use my invention, I will now desoribe ib byreference 130 the accompanyingdrawings, in which- Fignre 1 is a view of the upper corner of a winclow-sash, partly in sectsion, showing my i mproved device. Fig. 2 is a view of the box which contains the looking-cam. Fig. 3 is a. view of a modification. Fig. 4 is a view ofthe device oonstructed for use with a chain. Fig. 5 is a view of a modification.

In the opposite edges of the sasl1 a, ab the upper end, I drill horizontally in tl1e sash a hole ofsnitable size to receive a perforated box 101 case, d, (see Fig. 2,) wihin in, so that be end, Fig. l, is flush with th sides of thcgroove b wib hout and countersunk into the sash. The box 01 case d is preferably made as shown in Fig. 2, so thab the hole to receive ib may be drilled with an enger and the box or case slipped therein Wibh litble trouble und expense.

In the vertical opening of the box or case d is a eam, e, so journaled with relation tothefronb end of the box that the cord c can be inserted down between thern with ease, bot when in is drawn up Ehe cum shall bite thereon and turn up and clamp the cord firmly against the end of box (Z. The box d being inserted in the hole 01 opening und the sash put in place, the end of the oord c is pushed down into the grooves b and through me box d between the cam e and the closed end 0f the box, and is then drawn back again'stnhe edge of the carnwhich having turnecl back to perrnit its downward passage, rests against it. When oho cord is drawn back to fasten it, Ehe 02mm turns up and clamps it firnxly against the end of the box d. Ifit 1's desir ed to release Lhe cord, il: can be done by pressing down the Garn by means ofa piece of wire, f, 01 other thin narrow instrument inserted down in the groove b beside the cord c, as shown in Fig. 1. When tl1e cam is thus foroed back and hold therc, the cord c is releasedand can easily be drawn out. Ibmay be replaoed bypushingit downinto the groove again, as before described.

If desired, the cmn may bcreleased by means of a key or other instrument inserted through a. hole, i, in the side of the sash a and box d, and engaging the 02m1 either direcbly or by means of a hob thereon. I prefer, howexger, to use the wiref, as ib can easily be inserted down through the groove alongside the cord, and thereby obviates the necessity 0f cutating the sash.

The distinguishing characteristic of my improved fastener is thab the locking-cam may be disengaged from the sash-cord without removing the sash from ohewlndow-fr ame. 'lhis is 1nade possible by t;he position of the cam. 'Ihe oan1-box d is sets in the hole in oho sasl1 ab the base of Ehe groove b, so thatthc axis of the cam shall be back of the cord. In this way more rooxn is given for the motion of tl1e cam,

which may easily be pushed back by tl1e wire finto thc box. \Vl1enthe oam is S on the outside of the cord in the groove, as in prior clevices, the1e is necessarily bot; little room in whioh Lhe cum can work, und the bearings of the cam obstrucb the groove so mach thab a wire rod cannot be insertcd to engage and unlock 'he cum.
